MINTED AND HIP HOLIDAY CARDS has some of the coolest holiday card choices (besides mine on etsy, of course!)
The design I chose was by French designer Cecile @ Paper Lounge. Love her style! 
I then uploaded my photo (I had a lot of fun being creative with photoshop to add my face to Jackie's bod to create a sort of retro-spoof card this year) The process is so easy and snag-free. You basically just pick a winner from one of their hundreds of hip designs and upload your own photo (or in my case, just my face to someone elses' photo!) You add the text desired and they send you a proof via email for approval before it goes to press.
Easy as pie, quick as a wink and cute as a bug. I was very impressed. 
Check out their site for both HOLIDAY and NEW YEARS cards. You won't be disappointed!
